MAGHDTE FOR CLEANING BALLS.

Application filed January 14, 1922. Serial No. 529,851.

I cleaned or polished is held inproper position for the action of a power driven concave cleaninghead or brush, and in which a'turning or shifting of the ball from time to time by the operator can be attained in a ready and convenient manner, all as will hereinafter more fully a pear.

In the accompanying drawing Fig. 1, is a vertical sectional elevation o a machine embodying the preferred form of the present improvements.

Fig. 2, is a top view of the same.

Like reference numerals indicatelike parts in both views.

Referring tov the drawing, 1 designates an upright supporting frame preferably formed of structural metal rails fixedly secured together and provided intermediate of its height with a floor or platform 2 adapt ed to support a driving motor 3 usually of the electnc type as shown.

4 designates an enclosing shell of an in verted cup form attached at its lower end upon the platform 2 and formed at its up- Y per end with a'central bearing hub 5 for i .the carrying shaft 6 of the rotary cleaning head of the machine.

. 7 designates a'bevel gear wheel secured to the lower end of the shaft 6 in superimposed relation to the motor 3 and having. operative engagement with a bevel gear pinion 8 on the armature shaft of said motor to receive ositive rotation therefrom.

9 esignates the rotary cleaning head mounted on the upper end of the shaft 6 and having its upper face formed with a concave recess ada to receive a lining 10 of bristles, felt or otherusual cleaning or polishing material, with-said lining having a concavity corresponding with the convexity of the bowling or like ball to be 0perated on.

11 designates a. skeleton frame pivotally attached to the top of the frame 1 near the 'rear end of the same by pivot knuckles 12,

and having at its front end an operating handle or bail 1-3 and at its rear end a rearwardly extending arm 14 for connection with a balancing spring 15 or like means arranged intermediate of said arm 14: and the main frame 1 as shown.

16 designates a central ring carried by the skeleton frame 11 and having a diameter a fraction less than'that of the ball operated on, so as to form a support for said ball as the same is turned and manipulated at intervals by the operator during the cleaning or polishing operation. In the preferred construction shown in Fig. 1, the supporting ring 16 carries a facing or pads 17 of felt, in order that marring of the balls surface by contact with. the metal of the ring 16 is avoided during the above mentioned turning or shifting manipulation.

Havin thus fully described my invention what I c aim as new and desire to secure by Letters Patent, is

1. In a ball cleaning machine of the type described, the combination of a main frame,

a vertical shaftjournalled in said frame, means for imparting rotation to said shaft, a cleaning head mounted on the upper end of said shaft and provided with a concave cleanin recess in its upper surface, and an adjusta le holding frame having a central ring the orifice of which has a less diameter than that of the ball to be cleaned and adapted to provide a support therefor in the universal turning adjustment of the ball to successively bring the entire periphery there- 101f to cleaning contact with the cleaning 2. In aball cleaning machine of the type described, the combination of a main frame, a vertical shaft journalled' in said frame, means for imparting rotation to said shaft, a cleaning head mounted on the-upper end of said shaft and provided with a concave cleaning recess in its upper surface, and a holdin frame ivoted at one side of the main ame an having a central ring the orifice of which has a less diameter than that of the. ball to be cleaned and adapted to cleaning recess in its upper surface, a holding frame pivoted at one side of the main frame and having a central ring adapted for supporting engagement with a ball to' be cleaned or polished, and a balancing means for said holding frame. I

' 4. In a ball cleaning machine of the type described, the combination of a main frame, a vertical shaft 'journalled in said frame, means for imparting rotation to said shaft, a cleaning head mounted on the upper end of said shaft and p'rovidedwith a concave cleaning recess in its upper surface, a holding frame pivoted at one side of the main frame and having a central ring adapted for supporting engagement with a ball .to be cleaned or polished, and a. balancing means for said holding frame, the same comprising a spring connecting a rear extension of said holding frame to the main frame.

5. In a ball cleaning machine of the type described, the combination of a main frame, a motor mounted on saidv frame, an open bottom shell secured to said frame and enclosing said motor,.said shell having a central bearing at top, a vertical shaft journalled in said bearing and operatively connected at its lower end withsaid motor, and a cleaning head mounted on the upper end of said shaft and formed with a concave cleaning recess in its upper surface.

6. In a ball cleaning machine of the type described, the combination of a main frame, a motor mounted on said frame, an open bottom shell secured to said frame and enclosing said motor, said shell having a central bearing attop, a vertical shaft jourfnalled in said bearing and operatively connected at its lowerend with said motor, a cleaning head mounted on the upper end of said shaft and formed with a concave cleaning recess in its upper surface, and an adjustable holding frame having a central ring adapted for supporting engagement.

with a ball'operated on.

7. In a ball cleaning machine of the type described, the combination of a main frame, a motor mounted on said frame, an open bottom shell secured to said frame and enclosing said motor, said shell having a central bearing at top, a vertical shaft jour-r nalled in said bearing and operatively connected at its lower end with said motor, a cleaning head mounted on the upper end of said shaft and formed with a concave cleaning recess in its upper surface, and a a motor mounted on said frame, an openbottom shell secured to said frame and enclosing said motor, said shell having a central hearing at top, a verticalshaft vjournalled in said bearing and operatively connected at its lower end with said motor, a cleaning head mounted on the upper end of said shaft and formed with a concave cleaning recess in its upper surface, a holding frame pivoted at one side of the main frame and having a central ring adapted for supporting engagement with a ball operated on, and a balancingmeans for said holding frame.
